What is Botulism ?
It is a toxin that is produced by
the bacterium "Clostridium botulinum."
It affects all ages and groups of
ducks and other waterfowl.

How do they get infected ?
Botulism is everywere since it is
a spore that lives in the ground.
Spores can be found in hay,
fruits, vegetables and similiar
elements.

Spores are eaten by the waterfowl,
and passed through the intestines
without causing illness.In low oxygen
enviorments some of the strains
cause toxins.

It is the ingestion of these toxins,
rather than the organism itself,
that causes botulism. Decaying
organic matter, stagnant pools and
marsh weed at the edges of dams
during droughts provide low oxygen
enviroments suitable for the production
of toxin, which maythen be ingested 
by ducks and other poultry. Maggots, 
litter beetles and fly larvae
lying in this environment may provide
a secondary source of toxin if 
eaten by the ducks.


What to look for: Signs of Botulism

After the waterfowl ingest the
toxin they may become sick or
shows signs of illness within a few
hours or up to 2 days later. The
earliest signs are drowsiness,
weakness and incoordination.

Depending on the amount of toxin
ingested, the signs may progress
to drooping or trailing of the wings,
and paralysis of the legs, eyelids
and neck. Birds may experience
difficulty in breathing.The feathers
become ruffled and may be easily
plucked due to the paralysis of
the skin structures.

DEATH usually follows, although
some birds may recover.

How to control it :

Do Not leave decaying matter
around so that your poultry can
have access to it. Collect ALL
carcasses of dead ducks (all poultry)
at least once a day and burn or bury
all the remains from infected fowl.
Drain stagnant pools, and provide
clean drinking water for them
daily. Waterfowl play in drinking
water and it is important to keep
fresh water for them on a regular
basis.

Adding small amounts of
clorox bleach to their swimming pools
(If you use these for ponds or
for a watering system for your
waterfowl) will help decrease
the formation of algae around
the inside edges of these pools.
The bleach will not harm the
birds in small amounts, and is
similar in action to clorination

or our drinking water.

If you provide a proper, clean
and sanitary environment, the
likelihood of abotulism outbreak is
very remote.

"Immunization of ducks against
botulism is not widely practiced."
However, when birds are at risk,
consider vaccination with the type
C toxoid.
